I'm not saying you are a newb or trying to treat you as such. But the main medium takes the canon cake, unless the creators say otherwise and only one man out of a whole team is implying that happened. for all we know Kobayashi & Itsuno (the guys in charge) "no that doesnt fit" and and Bingo went and insisted on it once he was able to write something as freely as he wanted. its not like the relation between FMA and FMAB, where the story changes halfway through and are meant to be canon only to thier respective series. there isnt an alternate continuity with DF. DF should fall into the "Other Appearances" section, where non-canon but relevent info is at since it hasnt been officially sanctioned as canon. thats why in canon discussions DF is equivilent to Naruto knowing Utakata in the anime.
